The purpose of this study ie to examine the behavior of accounting changes and test how market respond to accounting changes, particularly focusing on IT firms and Venture firms. The study period ranges from 2000 to 2004 and the sample consists of 172 changes made by KOSDAQ-listed firms. The empirical results show that (1) there are some differences in the behavior of accounting changes between IT firms and non-IT firms and (2) the abnormal stock returns are more negative for IT firms than non-IT firms. In addition, The abnormal stock returns are more negative for non-voluntary accounting changes than for voluntary changes, and when reported earnings increase by accounting changes, abnormal stock returns are negative. But, there are no significant results about Venture firm and non-venture firms. These empirical results imply that accounting changes of IT firms transfer negative information to stock market. Unlike accounting changes of non-IT firms, those of IT firms could be signals on negative change of business environment or high possibilities of earnings management.
